Q: How much does it cost to clean or pressure wash a deck?

• <div><p>The average cost to professionally clean or pressure wash a deck is around $150, with prices typically ranging from $100 to $600. Several factors influence the final price, including the deck's size, material, condition, and how long it has been since its last cleaning. For a smaller deck of about 300 square feet, you might pay around $100. For a larger deck of 1,000 square feet or more, the cost could be closer to $300 to $400. Decks that are very dirty or haven't been cleaned in years may require more time and special detergents, which will increase the price. The deck's material also plays a role. Wood decks often cost more to clean because they require a gentle power washing technique to avoid damage. Composite decks are typically less expensive to clean, and cleaning a metal deck may cost around $100.</p></div>

Q: How much does a 12x20-foot (240-square-foot) deck cost?

• <div><p>For a 12x20-foot (240-square-foot) deck, you can expect to pay between $7,200 and $14,400. This cost is based on a general price of $30 to $60 per square foot. The final price will depend on factors such as the decking material, design complexity, deck type, location, and local labor costs. Keep in mind that add-ons will increase the total; for example, adding an under-deck drainage system to a deck of this size could cost an additional $7,700.</p></div>

Q: Do I need to seal the underside of a deck?

• <div><p>Staining and sealing the underside of a deck creates a moisture barrier but traps water in the boards, quickly leading to rot. No matter how well you seal the above deck, water still gets through via nails and screw heads on the surface. Allow this water to flow naturally under the deck, where it is routed through the drainage system.</p></div>

Q: Why is my deck leaning to one side?

• <div><p>The most likely causes of a deck leaning to one side are damaged deck posts, soil erosion, and inadequate deck footings. If you&rsquo;re not sure about the exact cause, the best option is to call a contractor <a href="https://www.angi.com/articles/how-hire-deck-building-contractor.htm">who can build a deck</a> to inspect the damage and recommend the best way forward.</p></div>

Q: Can I draw my own deck plans?

• <div><p>Yes, you can draw your own deck plans in many cases. However, you must know your local building codes and be familiar with carpentry principles. Even then, it's always best to run your plans by a professional contractor with experience building decks, whether you choose to DIY some of the build or not.</p></div>
